Uma kukhulunywa ngokuthiukwakha amapayipi, ukuqinisekisa ukuqina kwazo kanye nokumelana nokugqwala kubaluleke kakhulu.Amapayipi ensimbi yekhabhoni e-LSAW, eyaziwa nangokuthi i-Longitudinal Submerged ArcAmapayipi okushisela, kuyisinqumo esithandwayo ngenxa yamandla awo aphezulu kanye nokuthembeka kwawo. Ukuze kuthuthukiswe ukumelana kwawo nokugqwala, la mapayipi angambozwa nge-polyethylene enesakhiwo esinezingqimba ezintathu eyaziwa ngokuthi i-3PE. Kule bhulogi, sizohlola izinzuzo zokusebenzisaAmapayipi ensimbi yekhabhoni e-LSAW ambozwe nge-3PEnokuthi kungani ziyisinqumo esihle kakhulu sezimboni ezahlukene.
Isembozo se-3PE esilwa nokugqwala siyisisombululo esithembekile esivikela amapayipi ensimbi yekhabhoni e-LSAW ekugqwaleni futhi sandise isikhathi sawo sokuphila. Isakhiwo se-3PE sakhiwe ngezingqimba ezintathu, siqala ngesendlalelo se-epoxy powder esihlinzeka ngokunamathela okuhle kakhulu kanye nokubopha ebusweni bepayipi. Lokhu kulandelwa isendlalelo esinamathelayo, esiqinisa kakhulu isibopho phakathi kwe-epoxy kanye nesendlalelo sokugcina - i-polyethylene elwa nokugqwala. Isendlalelo se-polyethylene sisebenza njengesivikelo, sivimbela amanzi, amakhemikhali, nezinye izinto ezigqwala ukuthi zingafinyeleli ngaphakathi kwepayipi. Ngaphezu kwalokho, singamelana namazinga okushisa afinyelela ku-80°C, okwenza sifaneleke ukusetshenziswa okubanzi.
Uma kuqhathaniswa noqweqwe lwe-2PE, ukungezwa kwengqimba ye-epoxy powder kumapayipi ensimbi yekhabhoni e-LSAW ahlanganiswe ne-3PE kwandisa ukusebenza kahle kwezakhiwo zokulwa nokugqwala. Lolu qweqwe olwengeziwe luthuthukisa ukuqina nokumelana nokuguguleka, okuqinisekisa ukuthi amapayipi angakwazi ukumelana nezimo zemvelo ezinzima. Umbala ojwayelekile weAmapayipi ambozwe nge-3PEimnyama, futhi inamathela ezindinganisweni zomhlaba wonke ezifana ne-DIN30670, i-CAN/CSA Z245.21, kanye ne-ISO21809. Lezi zindinganiso eziqinile ziqinisekisa ukuthi amapayipi ahlangabezana nezindinganiso zekhwalithi kanye nokusebenza ezidingekayo, okwenza kube ukukhetha okuthembekile kwezimboni ezahlukahlukene.
Kwa-Botop Steel, singochwepheshe ekuhlinzekeni ngamapayipi ensimbi yekhabhoni e-LSAW asezingeni eliphezulu ane-3PE anti-corrosion coating. Amapayipi ethu atholakala ngobukhulu obuhlukene, amamaki, kanye nemininingwane ukuze ahlangabezane nezidingo ezithile zamakhasimende ethu. Ngokuzibophezela kwethu ekwenzeni kahle kanye nokunaka imininingwane, siqinisekisa ukuthi amapayipi ethu ahlangabezana nezindinganiso eziphakeme kakhulu embonini. Ngaphezu kwalokho, amapayipi ethu ambozwe nge-FBE anti-corrosion kusuka ngaphakathi, okuthuthukisa kakhulu ukumelana kwawo nokugqwala. I-FBE coating yangaphakathi ayinabo ubuthi futhi isiza ukuvimbela ukugqwala ngenkathi ithuthukisa izinga lokugeleza kwegesi kanye noketshezi ngaphakathiipayipiLokhu kwenza amapayipi ethu ensimbi yekhabhoni e-LSAW ambozwe nge-3PE abe ukukhetha okuthembekile kwezimboni ezifana namafutha negesi, ukuhlinzekwa kwamanzi, kanye nokwakha.
Ekuphetheni,Amapayipi ensimbi yekhabhoni e-LSAW ambozwe nge-3PEinikeza izinzuzo eziningi, kufaka phakathi izakhiwo zokulwa nokugqwala eziphakeme, ukuqina okuphezulu, kanye nokumelana nokuguguleka. Inhlanganisela yesendlalelo se-epoxy powder, isendlalelo esinamathelayo, kanye nesendlalelo se-polyethylene esilwa nokugqwala iqinisekisa ukuthi amapayipi angakwazi ukumelana nezimo ezinzima, okwenza afaneleke ukusetshenziswa okuhlukahlukene. Kwa-Botop Steel, siyaziqhenya ngokunikezaamapayipi asezingeni eliphezuluezihlangabezana nezindinganiso zomhlaba wonke futhi ezidlula okulindelwe amakhasimende. Tshala imali kumapayipi ensimbi yekhabhoni e-LSAW ambozwe nge-3PE ukuze uthole ikhambi lepayipi elithembekile nelihlala isikhathi eside.
